If you are making your own cable, only a few of the cutter pins will actually
need to be connected to the host computer. To ensure optimum results, the
cable length should not exceed 4.8 m (16 feet). It should be taken into
account that your computer or cutting software may also require additional
loopback connections at the host computer’ s end of the data cable.
• Connect the Transmit Data (TXD) pin of the computer to pin #2 of the
cutter.
• Connect the Receive Data (RXD) pin of the computer to pin #3 of the

computer to pin #4 or pin #7 of the cutter. Connect the Request To Send
